Molecular signatures of complex photodissociation reactions. All energy on earth comes from the sun, either directly (e.g photosynthesis) or indirectly (e.g fossil fuels). Photochemistry is the study of how this light is absorbed and what happens to a molecule afterwards. Despite significant experimental and theoretical advances in the past decade (some in our lab), scientists still cannot predict the outcomes of most photochemical reactions.

All energy on earth comes from the sun, either directly (e.g photosynthesis) or indirectly (e.g fossil fuels). Photochemistry is the study of how this light is absorbed and what happens to a molecule afterwards. Despite significant experimental and theoretical advances in the past decade (some in our lab), scientists still cannot predict the outcomes of most photochemical reactions. In this project we will determine the reactivity of several small, fundamental organic molecules. Not only are these molecules pollutants around our cities, but discovery of how they react in the presence of light will allow us to understand and predict the photochemistry of a much wider range of organic species.Read moreRead less

Summary
The Buckland Park Lidar Facility. This project will develop a laser radar (lidar) facility to operate as a test bed for studies in atmospheric physics, space physics, optics and astronomy.
Coherent LIDAR for Monitoring Air Pollution and Atmospheric Wind-fields. Industry, government and civil defence urgently require compact, field deployable sensors that can measure winds and monitor pollution in the atmospheric boundary layer. Without these sensors they are unable to measure and make informed decisions about windborne dispersion of industrial emissions, environmental pollutants, and chemical/biological toxins under operational conditions. The project will develop eye-safe cohere ....Coherent LIDAR for Monitoring Air Pollution and Atmospheric Wind-fields. Industry, government and civil defence urgently require compact, field deployable sensors that can measure winds and monitor pollution in the atmospheric boundary layer. Without these sensors they are unable to measure and make informed decisions about windborne dispersion of industrial emissions, environmental pollutants, and chemical/biological toxins under operational conditions. The project will develop eye-safe coherent lidar (light detection and ranging) systems that can measure wind velocities at ranges of up to 10 km with an accuracy of about 1 m/s, and can be deployed to field sites as required. The technology will be of major interest to the commercial sector.Read moreRead less
New insights into free radical reactivity via gas phase studies of radical anions. Free radicals are known to be critical reactive intermediates in chemical processes ranging from the formation of photochemical smog, through combustion to the onset of age-related diseases. This research increases our understanding of how free radicals react and will thus allow for more accurate prediction, and in some instances greater control, of the outcomes of chemical reactions and their health and environme ....New insights into free radical reactivity via gas phase studies of radical anions. Free radicals are known to be critical reactive intermediates in chemical processes ranging from the formation of photochemical smog, through combustion to the onset of age-related diseases. This research increases our understanding of how free radicals react and will thus allow for more accurate prediction, and in some instances greater control, of the outcomes of chemical reactions and their health and environmental consequences. New instrumental technologies will be developed and young Australian researchers will be trained here, and with collaborators in the USA, in state-of-the-art techniques (particularly in mass spectrometry) that are essential to our emerging technology-based economy.Read moreRead less
The best astronomical site on earth? A modern optical/infrared telescope is only as good as its site. We have previously shown that the infrared skies above the South Pole are up to 100 times darker than skies elsewhere, leading to enormous potential gains in sensitivity. We now seek to extend these measurements to Antarctic sites that are even higher, drier and colder than the South Pole. These are expected to be the best observing sites on Earth, paving the way for the deployment of telescop ....The best astronomical site on earth?

A New Digital Radar for Studies in Solar-Terrestrial and Atmospheric Physics. Australia is a world leader in the development of High Frequency (HF) radar surveillance systems, such as JORN (Jindalee over-the-horizon radar). However, Australia's ability to support these operations and remain a leader in these fields depends on its capacity to nurture expertise and train new personnel in these areas.

Australia is a world leader in the development of High Frequency (HF) radar surveillance systems, such as JORN (Jindalee over-the-horizon radar). However, Australia's ability to support these operations and remain a leader in these fields depends on its capacity to nurture expertise and train new personnel in these areas. The new HF radar system will play a crucial role in this respect, providing (i) high-level training in radar technology and associated science, (ii) a test bed for the development of new instrumental and data analysis techniques, (c) new information on the source of ionospheric perturbations that can affect the performance of JORN, and (d) data important for Australia's space weather prediction community, via IPS (Ionospheric Prediction Service) Radio and Space Services.Read moreRead less
A large aperture Sodium lidar for investigating the middle atmosphere (10-100 km). We will create a world-leading sodium lidar for remote sensing of the mesosphere and lower thermosphere (MLT) regions of the atmosphere, by developing a novel solid-state sodium light source and using the Cangaroo-1 telescope. It will provide the most accurate measurements ever of the temperature profile and wind velocities in the MLT for much needed input into models of the atmosphere.
